Safety equipment bag

ABSTRACT

The present invention relates to a bag for containing safety equipment. The bag includes a transparent surface and a slot. The surface has at least first and second lines of weakness. The slot is directly or indirectly associated with the lines of weakness. The first line of weakness and the second line of weakness converge.

TECHNICAL FIELD

This invention broadly relates to a safety equipment bag. More particularly, the invention relates to a breachable safety equipment bag.

BACKGROUND OF THE INVENTION

For public transport vehicles that run on airways and seaways, it is required by the law of most countries that items of safety equipment are readily available on board for passengers to use in case of emergency.

Each piece of safety equipment is commonly contained in a bag for storage. Existing bags in the marketplace typically include a mouth kept closed by a strip of Velcro™ having a label seal stuck thereon to indicate that the bags have not been tampered with. The label is however only a tamper-evident but not tamper-resistant feature. As such, the bags are still susceptible to tampering attacks.

Additionally, as a tamper-evident device, the label described above has the following shortcomings:

1. it is prone to peel off over time, particularly in a dry condition such as the cabin of an aircraft; this prompts special inspections to ensure that the bag has not been tampered with, which requires extra manpower and hence incurs extra costs; and

2. it requires manual inspection before each flight departure for security reasons; this is time consuming and hence increases airliners' operational costs;

It is an object of the present invention to provide a safety equipment bag which may overcome or ameliorate the above shortcomings, or which will at least provide a useful alternative.

Disclosure of the Invention

According to one aspect of the present invention, there is provided a bag for containing safety equipment, the bag including:

a surface having at least first and second lines of weakness;

a slot directly or indirectly associated with the lines of weakness;

wherein the first line of weakness and the second line of weakness converge.

Preferably, the bag has a side wall, the slot is generally perpendicular to the side wall, and the first and second lines of weakness are inclined to the side wall.

The bag may be made of any suitable material or combination of materials and may take any suitable shape.

It will be appreciated that although the bag of the present invention may be transported to and used in any selected location, it is intended to be placed in a public transport vehicle such as an aircraft or a ferry.

Preferably, the bag is a rectangular block and is made of at least two materials, one of which is transparent so that the safety equipment and details provided thereon are visible. More preferably, the bag has at least one transparent surface. Alternatively, the entire bag may be transparent or opaque.

DETAILED DESCRIPTION OF THE DRAWINGS

Referring to FIGS. 1 and 2, a bag 10 for containing safety equipment (not shown) includes a transparent surface 12, a slot 14 and a side wall 32. The surface 12 has lines of weakness 16, 18, 20 and 22 which are formed by perforations. Line 16 converges 25 with line 18 whereas line 20 converge with line 22.

As best shown in FIG. 1, the slot 14 is in contact with the ends of the respective perforated lines 16, 18, 20 and 22. It should however be noted that the slot 14 may be indirectly associated with the slot 14 in a sense that they need not be in contact with any one of the lines 16, 18, 20 and 22. In this embodiment, the slot 14 is located in the centre of the surface 12. The perforated lines 16, 18, 20 and 22 extend from the slot 14 towards the corners 24, 26, 28 and 30, respectively. Each of the lines 16, 18, 20 and 22 touches and ends at an edge of the surface 12.

Referring to FIG. 1, the bag 10 also includes additional lines of weakness in the form of score lines 44 and 46. Score lines 44 and 46 run parallel to the top and bottom panels 36 and 38 of the bag 10. Score line 44 has an end 48 which meets the ends of the respective converging lines 16 and 18 whereas score line 46 has an end 50 which meets the ends of the respective converging lines 20 and 22.

As best shown in FIG. 2, the bag 10 is a rectangular block and is made of a combination of two materials. The top, bottom and side panels 36, 38, 34 and 40 are made of nylon being stitched to the surface 12 which is made of a transparent material. This is advantageous in that the safety equipment contained in the bag 10 and any information printed thereupon such as a ‘use-by’ date is visible to a user.

The bag 10 may however also be made of an opaque material with a tag or label exposed outside of the bag 10 showing the ‘use-by’ date. In the event that the entire bag 10 is opague, a window can be stamped out using a jig and covered by a transparent material such that a specific area of the interior of the bag 10 is visible to the user. It is contemplated that the bag 12 may be cylindrical or take any suitable shape.

Referring to FIG. 2, the safety equipment 42 may be a life jacket, a fire blanket or a foldable escape ladder.

Turning to FIG. 3, bag 10 is another embodiment of the present invention having additional lines of weakness in the form of vertical score lines 52 and 54.

Referring to FIG. 4, bag 10B is a further embodiment of the present invention having two pairs of converging perforated lines 56 & 58 and 60 & 62. In contrast with the embodiments shown in FIGS. 1 to 3, the converging lines 56, 58, 60 and 62 of bag 10″ are not in contact with the slot 14.

Referring to FIG. 1, the slot 14 is reinforced by a plastic structure 64. The safety equipment 42 (see FIG. 2) includes an extension in the form of a tab 58 which passes through the slot 14 to be exposed outside of the bag 10. The slot 14 is stitched closed by a thread 66 which also engages a portion of the tab 58 of the safety equipment 42 such that the tab 58 is restricted to a desired disposition draping downwards.

Turning to FIGS. 5 and 6, bag 10C is a yet further embodiment of the present invention. Similar to the above embodiments, the bag 10C has a surface 12D with two pairs of converging perforated lines 80, 82, 84 and 86. The bag 10C also has a slot 14 which is defined by an eyelet 88, as best shown in FIG. 6. The eyelet 88 is made out of metal having a shape edge 90.

Referring to FIG. 7, the bag 10C has a breaching mechanism including a strap 92 and an hampering means 94. The strap 92 has one end 94 passing through the eyelet 88 and in use being exposed outside of the bag 10C. The end 94 folds back onto itself such that the end surface 96 reduces the likelihood of the end 94 being unintentionally or accidentally pushed into the interior of the bag 10C. The strap 92 has an opposite end 96 which is attached to the internal base of the bag 10C. The strap 92 is arranged such that it forms a loop 98 in the middle which receives the safety equipment (not shown). The strap 92 is also stitched to a folded elastic band 100 which holds the safety equipment in place.

As shown in FIG. 7, the hampering means is connected to the strap 92 and located inside of the bag 10C. The hampering means is in the form of a stud 94 having buttonlike upper and lower portions 102 and 104 with the strap 92 sandwiched therebetween. The stud 94 is located between the eyelet 88 and the elastic band 100. The stud 94 is spaced apart from the eye 88 such that when the end 94 of the strap 92 is pulled, the strap 92 travels a short distance so as to allow the stud 94 to gain some momentum before it hits the eyelet 88.

Referring to FIGS. 8 and 9, the bag 10C also includes a plurality of holes 106 which are provided in pairs in a surface 108 on the opposite side of the bag 10C. The holes 106 facilitate attachment of the bag 10C to a fixture such as the bottom part of a seat in an aircraft via suitable fastening means.

It will be appreciated that in all of the exemplary embodiments shown in the accompanying drawings, the lines of weakness are configured and arranged such that pulling of the tab 68 causes breaking of the stitching 70 and breach of the surface 12 along each of the lines of weakness, thereby allowing the safety equipment 42 to be drawn out of the bag 10, 10A,10B. It is contemplated that the perforated lines 16, 18, 20, 22 will be breached if and when thirty-five pounds of pulling force is exerted on the tab 68.

Turning to FIGS. 10 and 11, the bag 10C has a slide fastener 72 (also known as zipper) which allows placement or authorised retrieval of the safety equipment 42 from the bag 10C. The slide fastener 72 is associated with a tamper-evident device 74, the details of which are disclosed in international patent application number PCT/AU2007/000929 and will not be discussed here. It should be noted that the slide fastener 72 and tamper-evident device 74 are also provided in all of the embodiments described in this specification.

Referring to FIGS. 12 to 14, three further embodiments of the bag 10 are shown illustrating surfaces 12A, 12B and 12C, respectively. As shown in FIG. 12, surface 12A has two converging lines of weakness 106 and 108. The lines 106 and 108 join up with a somewhat rhombic area 110 defined by four lines of weakness 112, 114, 116 and 118. As shown in FIG. 14, there are two pairs of converging lines of weakness 120, 122, 124 and 126 all joining up to a rhomboid area 110 similar to that shown in FIG. 12. Additional lines of weakness 128, 130, 132 and 134 in this embodiment are provided to facilitate breaching of the surface 12B when the strap 92 is pulled. Turning to FIG. 14, the surface 12C has a pair of lines of weakness 136 and 138. Each line 136,138 has a first inclined section 140, a horizontal middle section 142 and a second inclined section 144. It is contemplated that an eyelet (not shown) is provided somewhere in the middle of the surface 12C. The eyelet may or may not be in contact with the middle section 142 of lines 136 and 138.

Turning to FIG. 15, a yet further embodiment of the bag 10 is shown having a side wall 149 and an end surface 146 which is transparent possessing two pairs of converging lines of weakness 148 and 150. The converging lines 140 and 150 join up with a rhomboid area 152 in which an eyelet 88 is located. The rhomboid area 152 is defined by additional lines of weakness 154, 156, 158 and 160.

As an alternative, the slide fastener 72 may be associated with a wirelessly detectable tamper-evident seal, the details of which are disclosed in international patent application number PCT/AU2010/000936 and will not be discussed here. Such a seal has a wireless detectable or readable portion, such as an radio frequency (RF) chip or a surface acoustic wave (SAW) chip, which is detectable or readable from up to 1.5 metres away by a remote detector (not shown). As such, regular inspections may be carried out remotely, swiftly and efficiently with the remote detector. Also, this is advantageous in that theft may be prevented if a detector is placed near an exit of a public transport vehicle carrying one or more bags 10C.

Those skilled in the art will appreciate that the invention described herein is susceptible to variations and modifications other than those specifically described. For example, the surface may be part of the bag or a panel of the bag. When the bag has a transparent part, this is in the form of a panel forming the surface. Each line of weakness may be formed in any suitable way, including scoring, perforating, or a combination thereof. Each line of weakness may also take the form of a plurality of holes or depressions. Furthermore, the lines of weakness converge but may do so without actually meeting. Other than those illustrated in the accompanying drawings, the lines of weakness may present in various patterns. All such variations and modifications are to be considered within the scope and spirit of the present invention the nature of which is to be determined from the foregoing description.
